Re: ►AMK GB◄ ~ SF-AW210 Diodes $10 Each Yes... already paid, too! as noted in the previous page: it's only 6 pages...:rolleyes:

Re: ►AMK GB◄ ~ SF-AW210 Diodes $10 Each :thinking: I'm sure your spell-check passed that, but you may want to state that differently... unless Niko has found a novel way to manufacture diodes (maybe "OrganicLED's?)

Re: ►AMK GB◄ ~ SF-AW210 Diodes $10 Each YES wth, I've been checking my email all last night, and never got a notification of your post... I think :thinking: Anyway, yes I'll take them - Paypal sent. Thanks! DanQ

Re: ►AMK GB◄ ~ SF-AW210 Diodes $10 Each your eyes must be younger than mine ;) I just remembered... this photo is on the first page - read the text, and look carefully at the photo: A bunch of sleds I got inexpensively a while back were all damaged to some degree - that's how the price was...

Re: ►AMK GB◄ ~ SF-AW210 Diodes $10 Each looks like it got run over by a truck... I notice that the box is bent - what was the outer container, a bag/envelope or a box? what was its condition? it would be helpful if the thing you're photographing was the part in focus... nice shots of the desk...

Re: ►AMK GB◄ ~ SF-AW210 Diodes $10 Each If Pyro doesn't respond in time, I'll buy his 10, and re-sell to him (non-profit) if he wants... :angel: :thinking: maybe I can trade them for some of his handy hardware! :eg: DanQ

Re: The REAL Kryton GB round #3 I also prefer 18650 with a boost or SEPIC driver; but if you must use 2 cells, how about 2 x CR123a ? iirc, they're just a bit narrower and half the length of an 18650... there may be a minor length issue - but I think the CR123a (aka 16340) will fit inside the...

oops! that was a dumb post (mine)... of course that critter doesn't pulse the output in any reasonable way after it goes through the inductor it's no where near square. Sorry 'bout that - my spine was screaming at me so loud this morning that I couldn't hear my brain. So you might say that made...

How's the LM3410 ?

[br][br]Re: the eye -[br] safety first: that cellular sensor can only average the pulses if it isn't burned out by one of them! or several in fast sucession... [br]Averaging: is going to be different for different wavelengths because of the receptors' non-linearity; and different for different...

No, I don't think so. Benm measured the average output power, and called it visibility in his conclusion. But visibility is how the eye perceives it, not how a thermopile averages it! I'm betting there is quite a difference between them. That's science for you though - analysis of experimental...

not anytime soon, I think - but I'd like to, and sometimes that gets things re-arranged... maybe after I get the taxes done, and this house re-finance papers turned in... But I would observe that these laser diodes we're using come from DVD writers and use very short pulses to burn pits into...

you're mostly right. You could 'dim' the laser by changing the pulse width or rate; as long as the rate is above a threshold (60-70Hz) your vision perceives it as a dimming effect. I use PWM DC-DC regulator chips (LM3410, LT1610) in current-regulated drivers; they put out a rather smooth...

do you mean one that uses PWM to regulate current? Check out Drlava's, I believe it does (and maybe others too). if that doesn't do it for you, maybe explain more what you mean. :beer: Danq

Re: The REAL Kryton GB round #3 maybe... have you seen this post? Kenom's homeless prevention sale bummer - if I wasn't on the edge myself I'd want to help out DanQ

Since this is an art piece... presumably it will be displayed in some place - where people might be close to it? Not to be a wet blanket, but: If that beam is anywhere that a person could possibly get anything into the beam (an eye, or anything shiny; a small hand with a ring?) then you'd...

This doesn't address your original question, but... Caution - when you measure the current with the meter in series with the LD, you may not be measuring the actual current that will flow without the meter in there (this is called "insertion loss"). The amount of difference will depend on...

:gj:Good shooting, Mike - right on target! You just saved 6 little jars of LodeStar solder paste... need any? :thanks: DanQ

thanks Mike - already tried water, I'll try the alcohol. (and I have one of 'em soaking in laquer thinner just for kicks)(unless the container got dissolved - better go check on that one...) :) DanQ

agreed... and I like Newark, too. But at $12 for 5cc, your idea of 'cheap' is different from mine! I meant 'inexpensive', which to an economy in the shape mine's in, that means "dirt cheap" ;) Thanks for the help though! :) DanQ
